How to upload and manage images with the DreamCompute dashboard

An image is a single file that contains a bootable operating system. Images are used to create instances within DreamCompute. This article describes how to upload, update, and delete an image using the DreamCompute dashboard. For information about creating image files, see the OpenStack Virtual Machine Image Guide.

Make sure the image file you are uploading in the DreamCompute dashboard is not larger than 2–3GB. Attempting to upload a larger file will likely result in an error message.

Large image files can only be uploaded using the OpenStack command-line client. For examples, see the following articles:

• DreamCompute command-line interface cheat sheet
• Launch an instance using an ISO image file with the OpenStack CLI

1. Navigate to the DreamCompute page.
2. Click the View Dashboard button to log in to your DreamCompute dashboard.
3. Click the Project tab in the left pane to expand the menu.
